MoRE than 400 people joined the search of woodland yesterday for missing clubber Sian O'Callaghan.

Friends of Miss O'Callaghan and her boyfriend Kevin Reape went on organised police searches of the 4,500-acre Savernake Forest area, near Marlborough, Wilts.

Local people -- many of whom did not know Miss O'Callaghan -- joined in the search of the thick undergrowth.

Mr Reape is also believed to have joined the hunt for his missing girlfriend, who was last seen leaving the Suju nightclub in Swindon in the early hours of Saturday.

So many people turned out to assist the search effort that by mid-afternoon police had asked for no one else to come to help.

Volunteers were divided into groups and each team went off with a specialist police officer.

Among those joining the search was labourer James McMurray (20) from Swindon, who explained why he joined the search: "I just wanted to do my bit," he said. "Nobody deserves to go through that and I'm doing my bit for the community."

His friend, Nick Glover (22), also from Swindon, said: "We've come to help as it's quite dreadful what's happening.

"We're just hoping we find her. We'll do anything to help the investigation."
